Display issues with radar level transmitters
Thread Content
I have a few tanks here that use reused level transmitters. I reset the address and range of these transmitters and installed them; however, the display on the transmitters shows a value other than zero, although the actual liquid level is zero. I would like to know what the reason for this is, and how to make the display show zero, matching the actual level.
Set the parameters as specified in the transmitter manual, such as tank height/empty mark/full mark/dielectric constant, etc； The specific methods for setting up the radar vary slightly depending on the brand
Ensure the parameters are set correctly, then save them. Try turning off the power and restarting.
It’s best to check the instructions to see how to make the settings; also, check whether there is any stirring mechanism inside the tank that might interfere with electromagnetic waves, leading to false detections. Reconfigure the settings for empty and full tanks, etc. Another important point is to filter out false signals. I hope this helps you
Pay special attention to the setting of the empty mark; it seems to be set too high.
